A. x linked dominant

C, x linked recessive

Answer 1

He cannot be merely a "carrier", because the Y chromosome typically will not have a dominant normal gene to keep the disease from being expressed. To give the disease to the daughter, it must be on the X chromosome. From the way your question is phrased, it is either A or C.
